I used UniWS (an unofficial patcher) to adapt the game to use a resolution of 1366 pixels by 768 pixels. It worked, and only some of the icons appear stretched now. However, now, I can't see the conversation options. They're lower than the screen shows. I can tell because they aren't there, but also because the black bars that appear during in-game cutscenes are smaller. How do I fix this?

For example, this is a different widescreen resolution, but the dialog works fine (it's 16:9 in the picture below):
